3. The antigens for ABO and Rh blood groups are present on ____________
b) white blood cells
c) red blood cells
Explanation: Red blood cells are the most common type of blood cells and principle means of delivering oxygen. The antigens for blood groups are present on RBCs.
4. Which of the following blood group is referred as a universal recipient?
Explanation: Blood group AB is referred as a universal recipient. They can receive donated blood of any ABO blood group.
5. What are the two blood tests?
a) Rh and ABB
b) ABO and Rh
c) ABO and Rn
d) ABC and Rh
Explanation: The two blood tests are ABO and Rh type. ABO test determines the blood group. Rh test determines if it is positive or negative.
6. What is the process of transfer of human blood known as?
Explanation: Blood transfusion is the process of receiving blood or blood products into ones circulation intravenously. It is used in various medical conditions to replace the lost component of blood.
7. Which is the rarest blood group?
a) AB negative
b) AB positive
c) O negative
d) O positive
Explanation: AB negative is the rarest blood group. It is seen only in 1% of US population.
8. Who discovered blood groups?
a) Thomas Cooley
b) Karl Landsteiner
c) Camillo Golgi
d) Ernst Haecker
Explanation: Karl Landsteiner discovered ABO blood group system. He is an Austrian scientist. It was discovered in 1900.

10. If the blood group of an individual is A then the antibody present is _________
a) Anti B antibodies
b) Anti A antibodies
c) Anti O antibodies
d) Anti OA antibodies
Explanation: If the blood group of an individual is A then the antibody present is Anti B antibodies. It is present on RBCs.
11. Which blood type can be transfused to the individual whose blood type is unknown?
a) AB positive
b) AB negative
c) O positive
d) O negative
Explanation: O negative blood type can be transfused to individual whose blood type is unknown since it is a universal donor blood group. Only6.6% of population has O negative blood group.
